First of all, when asking a question and then later on changing it, it would be nice if you mentioned the question has been updated or modified. That way people that replied to the original question won't look as though they're talking out of their insert favorite bodypart here. As for the actual regex, you asked for all the data, so by that I assume you don't want to get rid of any html tags. I'll also assume you mean TRNsquare_thingy instead of the other way around... `use strict; use warnings; my $blurb = 'Starting the , text and there are more TESTBPR<b>PE12. +3AZ234anything, BPR set ? & @ TRN $ ?of charactersCan be anythin +g BPR* TRN# in here79something here11<b>TRN1 1415161718P +E12.3AZST21st371718PE12.3AZST21stand so on and more text fol +lows'; #035 is the octal for that squarethingy you got there... $blurb =~ /\035BPR(.+)TRN\035/; print "result: $1\n";` [download] Remember rule one...

This is a confusing question because there are several BPR's and TRN's, and you don't say whether you want the match to be greedy (everything from first BPR to last TRN) or non-greedy, or whether you want multiple matches returned. I'm guessing the latter, but my grasp of regex is still too weak to get it to return: `<b>PE12.3AZ234anything, BPR set ? & @ ` [download] instead of: `set ? & @ ` [download]	[reply] [d/l] [select]

It seems like malformed data is breeding a malformed question here. If it is to be assumed that you truly want to find thing between BPR and TRN identifiers, then your desired output should be `<b>PE12.3AZ234anything, BPR set ? & @` [download] and `` [download] which doesn't seem logical, which brings me to my original statement, malformed data breeds a malformed question. what kind of data is this and who's generating it? (If you're at liberty to say that is The regex however looks like the one above + minimal matching`m{BPR(.)?TRN}` Grygonos	[reply] [d/l] [select]
